Beat 2 eggs, finely chop carrot and onion and add them in, then stir in ground black pepper and half a tablespoon of tuna sauce. Add half a bowl of rice, mix well, then roll it up like an egg roll.
Crack the eggs into a bowl and beat well.
Mix the rice with salt and sesame oil until fluffy.
Heat a pan with oil over low heat, pour in the egg mixture, and spread it thinly.
Place the rice on top of the egg and spread it evenly.
Roll up the egg and rice together tightly.
Keep rolling and cooking until golden brown on all sides.
Cut into bite-sized pieces before serving.
